ADDING-MACHINE.

Application led 'February 15, 1916.

To all whom t may concern:

Be it known that I, CLAIBonNn W. GoooH, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented new and useful Improvements in AddingNIachines, of which the following is a speciication.

The present invention relates to the keydriven class of adding machines which do not ordinarily have any printing equipment. It is frequently desirable in the carrying on of calculating work through use of machines of this sort, to be able to preserve a grand total of the sums o f several series of additions or computations. Ordinarily these machines have a single set of registering wheels and when so equipped there is noV way of preserving a registration of a sum or total while another is being accumulated. The purpose of my present invention is to enlarge the capacity of machines of this class by providing an additional set of accumulating wheels and so relating them to the key-driven actuating mechanism or to the regular set of wheels, that the registration of sum or total may be preserved upon this additional set of wheels while the regular set is returned to Zero for the commencement of a new series of registering operations, the sum total of which may be added to that. preserved upon the additional set of wheels. In carrying out my invention I provide for using the machine in the ordinary way, as a single accumulator machine, and I provide for bringing into play the additional set of wheels at the will of the operator in order that registrations may be made simultaneously upon the two sets of wheels, and I further provide for resetting the regular set of wheels to Zero without affecting the additional set of wheels. Provision is also made for simultaneously resetting both sets of wheels to Zero.

In the construction here shown the additional set of wheels is located forward of the regular set of wheels and transmission gearing is employed between the two sets of wheels and a gang of clutches which may be opened and closed at will so that registration lnay be effected upon the regular set of wheels only, or may be elfected simultaneously upon the two sets of wheels. Zeroizing mechanism is provided for each set of wheels, that for the regular set of wheels being actuated by the stroke of a Specification of Letters Patent.

hand-lever, as usual, and that for the additional set of wheels being arranged to be coupled with and uncoupled from the zeroizing mechanism for the regular set of wheels. The opening of the aforesaid clutches to disconnect the additional set of wheels from the regular set of wheels is accompanied by locking of the additional set of wheels against turning, and provision is made for unlocking those wheels as an accompaniment to the coupling together of the two Zeroizing mechanisms. Provision is furthermore made for opening the clutches as an incident to the coupling together or said mechanisms because, with the two sets of wheels carrying differentregistrations, they should not of course be geared together' when simultaneous Zeroizing of them is to be practised.

In the drawings which accompany and form part of this specilication, Figure l represents the front portion of a machine of the class concerned, the same containing one form of embodiment of my present invention and the parts appearing in right-side elevation except that the inclosing casing is in section and .a supporting frame-piece is omitted and certain rods and shafts correspondingly appear in cross-section; Fig. 2 is a sectionalized plan view of the same portion of the machine, which is represented as aterally condensed; Fig. 8 is a top plan view embracing only a limited portion of what is illustrated in Fig. 2, the parts being shown on an enlarged scale as compared therewith and under an adjustment which provides for simultaneous registration upon the two sets of wheels; Fig. 4L is a similar view illustrating a somewhat different condition, to wit, that brought about through the setting of the special key which provides for simultaneous Zeroizing of the two sets of wheels; Fig. 5 is a vertical section taken substantially on the line 5-5 of Fig. 2 and illustrates parts at the left-hand side of the machine set for simultaneous registration of amount-s upon the two sets of wheels; Fig. (i is a similar view illustrating the effect upon these parts of operating the aforesaid key which provides for simultaneous Zeroizing` of the two sets of wheels.r while the other special key, which provides for simultaneous registration upon said wheels, remains down; Fig. 7 is a sectionalized view in side elevation of the duplex. accumulating mechanism shown upon a somewhat larger scale than in Fig. l and with various parts omitted and others broken away, the particularcondition depicted being that under which the regular set of wheels register Zero, with the zeroizing liaiid-lever drawn forward, whereas the additional set of wheels is unaffected by the operation of said hand-lever and continues to register a total; Fig. 8 is a cross-section taken substantially on the line 8-8 of Fig'. 2; Fig. 9 is a vertical crosssection taken substantially on the line 9 9 of Fig'. 5;"Fig. l0 is a vertical cross-section taken substantially on the line 10-10 of Fig. 5; Fig. 1l is a vertical cross-section taken substantially on the line ll-ll of Fig. 2.

So far as the machine proper is concerned, comprising the equipment of numbered keys and they levei's upon which they act and the means vfor measuring the extent of movenient theieof and transmitting the movement to the regular set of adding wheels, no detailed description need be given because that is all disclosed in one or more prior patents. s

In the present drawings only the forward portions of the column actuators F appear, as in Fig. 1, and the stems of a few of the numbered Vkeys F which drive said actuators, appear in horizontal section in Fig. 2. The reference letter A designates the numeral wheels composing the i'egular set, the same being located as usual within the for- =ward part of the inclosing casing Z to be read through sight openings a in the top of said casing. The reference A designates the gear Awheels arranged as usual immediately adjacent the said vnumeral wheels and being the elements of the regular accumulating mechanism which directly receive measured movements in clockwise direction as the same are transmitted from the coluinn-actuators through the medium of operating connections identical with those illustrated and described in the aforesaid patent.

In carrying out the present invention the second set of wheels AX is located within the casing forward of the regular set of numeral wheels, the casing' being extended sufficiently for the purpose and provided with a set of sight openings a through which to read this additional set of wheels. Planetary `gearing of the same sort as that associated with the regular numeral wheels, is employed in connection with the extra set of wheels, and this gearing is controlled and operated for purposes of transmitting carrying impulses from wheel to wheel of the extra set, by mechanism substantially dupli eating that employed in connection with the regular set of wheels. The gear wheels immediately adjacent the respective numeral wheels AX, and corresponding with the before-identied gear whels A, are designated by the numeral 25. They are of somewhat smaller diameter than the gear wheels A', owing to the character of the transmission gearing, presently to be described, which intervenes between the Vlatter and said gear wheels 25, and the planet pinions DX, carried by the latter, are laterally displaced as compared with the regular planet pinions D, inasmuch as the gear wheels 25 are not of such diameter as to permit of said planet pinions DX being' accommodated between the peripheral portions of thesegear wheels and the sun gears E". This slight difference will be readily discerned upon comparison of F 8 and 1l.

Upon a i'od 26 extending through the framework of the machine midway between the two sets of numeral wheels, gear wheels 27 are journaled, said gear wheels being constantly in mesh with the gear wheels A iespectively. ininediately adjacent these gear wheels 27 to the left thereof, gear wheels 28' of smaller diameter are j ournaled upon said rod as best shown in Fig. 10, and these latter gear wheels are constantly in mesh with the gear wheels respectively. Obviously if the gear wheels 27 and 28 are rotatively con nected together, any movement imparted to the gear wheels A will be transmitted to the gear wheels 25.

llrovision is made for rotatively connecting and disconnecting gear wheels 27 and 28 at will as follows: The web of each gear wheel 27 around the hub has a circular series of clutch holes 27a, and a sliding clutch Yclutch holes 27a and withdrawing it therefrom. There is of course a series of these yokes, as illustrated in Fig. 2, one for each of the clutch sleeves, and they are suitably confined upon the shaft 32 against lateral movement relative thereto.

vShifting of the said shaft 32 of course shifts all of the yokes and the clutch sleeves so as to simultaneously connect or disconnect the gear wheels 27 and 28 of the several pairs and thereby bring into action or throw out of action the numeral wheels of the for ward or extra set. I Vprovide a depressible key 33 'for shifting said shaft, this key being preferably located at the left of the keyjboard of the machine. The stem 33a of said key is preferably notched as at 331 for engagement with the keyboard plate Z', as shown in Figs. 5 and 6, to keep the key depressed in opposition to the spring 34 which normally holds it up. The operating connections between said key and the laterally shiftable shaft 32 are of the following description: A stud 33C on the key stem engages a slot in the rear end of a bell crank lever 35 and the depending branch of the latter has a stud 35a occupying a slot in the rear portion of a bar 3G. The rear portion (Fig. 2) of this bar stands on edge vertically whereas the laterally and thence forwardly extending portion of the bar lies horizontally, the same having an obliqnely extending terminal portion pivotally united with one arm of a bell crank lever 37 the other arm of which embraces a collar 3:2a on the shaft 32. Obviously depression of the key 33 will operate to thrust forward the bar 36 and shift the shaft to the right, and this will in turn clutch together the wheels 27 and 2S of the respective bars. Upon release of the key the spring 34 will obviously function to unclutch said gear wheels.

Manifestly with the said gear wheels clutched together simultaneous registration of amounts upon both sets of numeral wheels will result from operating the numbered keys of the machine. Thus both sets of wheels may be caused to accumulate the same total. Then by release of the special key 33 the rear or regular set of wheels will be disconnected from the front or eXtra set of wheels, and may then be independently Zeroized in preparation for accumulating a new series of amounts. By again setting down the key 33 that new series of amounts will be simultaneously accumulated in the forward set of wheels and added to the pre vious total reserved upon that set of wheels. Thus a succession of totals of different series of amounts may be separately accumulated upon the regular set of wheels, and a grand total registered upon the forward set of wheels. Of course it will be obvious that where the work in hand calls for but a single accumulator, the special key will not set of wheels to Zero includes a rock shaft S' rotated anti-clockwise by forward pull of the hand lever lV 2), and carrying a crank plato ll having a stud 12 in a cam slot of a lever 13. The latter is forked to engage a stud on a crank arm 10 of a rock shaft 10 having flattened sections to operate upon backstop pawls R, disengaging them from ratchet wheels E2 and causing them to disengage driving pawls f) from said ratchet. The rocking of shaft 10 (through its camarin 10b) also shifts journal rod 1), to laterally displace overthrow preventing toothed disks 1G, further freeing the gears for backward turning. Springs J so turn the gears and numeral wheels through the medium of segments II and their connections the details of which are shown and described in the Horton Patent No. 1,243,839 issued October 23, 1917. To cause said segments to so operate the gear disks are locked by hooked levers 2 thrown into the paths of studs E on said disks by a bail cross-rod occupying' cam-slots of the levers 2, one side of the bail being part of the aforesaid crank-plate 11. Said cross-rod also occupies cam-slots of stop levers 'having hooks Ll to intercept lugs Z on the respective numeral wheels for preventing their backward turning beyond the zero position.

Provision is made for Zeroizing the forward set of wheels in the same way that the rear set is zeroized, that is to say, by backward rotation under action of the carrying springs X. As before stated the carrying mechanism of the extra accumulator is identical with that of the regular accumulator. I may here add that the devices for acting upon the gear disks CX in a zeroizing operation, and for stopping the wheels AX at Zero, are identical with those performing similar functions in connection with the rear set of wheels A, and I have applied the same numerals to corresponding parts associated with the forward set of wheels using the suflix X as in the case of other reference characters already employed in this specilication. There is no occasion, however, foil employing in connection with the forward set of wheels the devices hereinbefore referred to which require disablement as a preliminary to Zeroizing the rear set of wheels and no such devices or disabling mechanism appear in connection with the forward set of wheels. It will be understood that those devices, as directly associated with the real' set of wheels, exercise control. also over the forward set of wheels, inasmuch as the latter are driven for registration purposes only through the transmission gearing which connects` them with the regular set of wheels. When disconnected from the latter and so no longer under the control of said devices, it is desirable that the forward set of wheels shall be locked against any accidental turning and this I provide for by equipping the clutch sleeves 30 with locking pins or studs 40 to engage holes in plates 41 surrounding the rod 26. Each of these plates has a circular series of holes -rll corresponding in number with the clutch holes 27a in the gear wheels 27 so that to whatever' position the associated clutch sleeve 30 may have been turned, its locking stud 40 will enter one of the holes 4l when the shaft 32 is shifted to the left. Obviously the numeral wheels AX will thereby be locked against rotation. h

The zeroizing mechanism for the forward set of wheels includes a rock shaft SX corresponding with the rock shaft S, and I provide for operatively connecting these two rock shafts together so that the forward set of wheels may be zeroized by the act of pulling forward the hand lever W, and I also provide for the unlocking of the forward set of wheels as an incident to the coupling together of said rock shafts. For the purposes of this coupling together of the rock shafts the before-mentioned crank-arm 11, secured to the left-hand end of the rock shaft S, has formed integrally with it an upwardly extending arm 11a carrying a stud 11b. Similarly the left-hand bail side-arm 5X of the forward Zeroizing mechanism has formed integrally with it an upwardly extending arm 42. A link 43 is pivotally connected to the upper end of said arm 42 and extends rearwardly adjacent the arm 11'll where it is formed with a notch 43a to engage the stud 11b. The normal condition is illustrated by dotted lines in Fig. 1 and the same condition is illustrated in Fig. 5. The forward side of the notch is above the stud so that rocking of the shaft S does not affect the shaft SX. Lowering of the link 43 engages the notch with the stud as shown in Fig. 6 and under these conditions the rocking of the shaft S is accompanied by a rocking of the shaft SX.

The lowering of the said link 43 is accomplished by depression of a special key 44 which is located at the left of the keyboard forward of the key 33. The stem 44a of this key carries a stud 44b which occupies an arcshaped slot 43b in the rear end of the link 43. Said key is normally upheld by a spring 45 and upholds the said link, but obviously whenthe key is depressed the link will be forced down and the connection established between the rock shaft SX and the regular shaft S, as illustrated in Fig. 6. The depression rof this key also unlocks the forward wheels, this being effected by shifting the lock plates 41 to the left through the medium of connections I shall next describe.

The before-mentioned key stud 44b is eX tended to the left, as best shown in Fig. 9, and occupies a cam slot 46a in the lower arm of a lever 46 which is pivoted upon a frame stud 4S. The upper arm of this lever is pivotally connected to a bar 49 of a char acter similar to the before-described bar 36. Thus the rear portion of this bar 49 is set on end vertically and its forward portion lies horizontally.A This forward portion is pivotally connected with one arm of a bellcrank lever 50 2), the other arnji of which embraces a collar 51u on a laterally shiftable rod or shaft 51. The aforesaid lock-plates 4l constitute extensions of the side arms of a series of yokes 41'D which are mounted upon said shaft 51,suitably confined thereon against any relative lateral movement. Depression of the key 44 rocks the lever 46 from the'position shown in Fig.

5to that shown in Fig. 6, and therefore thrusts the link 49 forward land shifts Vthe 'shaft 51 to the left. The lock-plates 41l are free to slideupon theV rod 26 and the said shifting of the shaft 51 shifts the lock-plates disengaging them from the several lockstuds 40, thereby freeing the forward wheels for backward rotation. For the purpose of additionally supporting and steadying the lock-plates I prefer to provide them with downward extensions slotted to embrace a cross rod 52, as illustrated in Figs. 5 and 6.

Manifestly no attempt should be made to simultaneously zeroize the two sets of wheels when they are geared together, for after the first series of amounts have been simultaneously registered upon the two sets of wheels and the regular set has been zeroized, the two sets of wheels will not register the saine thing and if geared together both sets could not be simultaneously Abrought to zero. Of course if the key 33 is up no such thing has to be taken into account, but that key may be down at the time the zeroizing key 44 is depressed. Hence T provide for disconnecting the two sets of wheels by the pull on the hand lever TV at the outset ofra zeroizing operation, in case the key 33 happens to be down. To this end the bar 36 is slotted, as before mentioned, to receive the stud 35a. A spring 53 connects that stud with a stud at the rear end of said bar 36 so as to provide a yielding connection between the bell-crank lever 35 and the bar and therefore make it possible to operate the bar independently of the key 33, forcing it rearward to open the clutches and vdisconnect the two sets of wheels. Ou the cross rod 14 which supports the gear sectors E I journal an arm 60 which extends forward of a shoulder 36c (Fig. 2) of the bar 36. Said arm is widened at its middle portion and the forward edge 60a has a cam relationship with the before-mentioned roller 12. Tf the key 33 is down as shown in iFig. 6 the forward thrust of the bar 36 will have swung the arm 60 forward to the position shown in full lines. Then when the shaft S is rocked at`the outset of a zeroizing operation the roller 12 will force said arm 60 rearward and thereby force the bar 36 rearward so that the wheels will be disconnected just as though the key 33 'had been released. The upper half of the forward edge 60L of the arm 60 is concentric with the shaft S as the zeroizing operation continues so that the stud 12 will then traverse said edge idly.
